System and method for a health status display based on detected magnetic nanoparticles

ABSTRACT

Methods are disclosed for displaying a health status on a user-worn or carried device comprising of disposing a magnet within a housing of the user-worn or carried device, configured to detect a magnetic field supercutaneously, wherein the field is generated by an interaction of the magnet with magnetic nanoparticles of a delivery agent delivering a therapeutic or vaccine intravenously, converting the detected magnetic field into a field-specific electrical signal and outputting at least one of a pre-defined color, symbol, or audio-coded display on a display portion of the user-worn or carried device signaling the user health status based on the converted field-specific electrical signal.

RELATED U.S. APPLICATIONS DATA

This application claims priority under 35 U.S.C. 119(e) of provisional patent application No. 62/603,163 filed on May 17, 2017, entitled “Non-verbal Person to Person Line of Sight Electronic Communication Protocol Standard”, which are hereby incorporated by reference in their entirety.

FIELD OF INVENTION

The present invention relates to certifying displays from user-worn or user-carried (mobile) devices, and more particularly, relates to a digital health credentialing system and method that does not require accessing a remote registry.

BACKGROUND OF INVENTION

Badges have long been a mainstay in public gathering situations as a way to identify the people engaged in the public gathering. It has also been a primary way of communicating to others a level of credential to facilitate access or a professional process. While the badge has long been simply a name card, with title, and possibly a photo, they have recently morphed into digital versions. Digital badges may be operatively coupled to networked devices and be enabled to reconfigurably display items. According to one embodiment disclosed and claimed by Identity Systems, Inc. (US20150348498), the digital badge device may include a mounting means, power source, microprocessor, memory, and display to receive and display digital content from a network device according to a pre-defined rule. Identity Systems badge may be associated with an individual or employee, and then automatically display at least the name of the individual or employee based on the association and the pre-defined interaction rules between the digital badge and networked device.

Identity Systems digital badge does not disclose or claim for any digital interaction between digital badges. In other words, the badges are not configured to communicate between badges or share digital content between badges or from badge to networked device. Therefore, the badges are simply contemplated as being a visual display of identity or group/brand association—that may be dynamically displayed according to a pre-defined rule. However, it is not envisioned to serve as a true digital communication tool, that may interact with other badges, and push digital content from one badge to another badge—in a dynamic and targeted fashion. Additionally, badge-displayed content or badge-badge shared content is not enabled for social media sharing or inclusion into a running virtual footprint of a badge wearer. What's more, without tracking of such a virtual footprint, behavior or influence ratings cannot be accurately identified in order to dynamically push targeted content.

Aside from a lack of badge-badge or badge-device interactivity or footprint tracking for targeted content delivery, digital badges lack a system or protocol for communicating an approach or further engagement of digital content interaction. More specifically, badges, such as Invent Systems, lack a symbol or color-coded display cue between users who are in their ‘line of sight’ (or groups of people) for communicating a permission to approach, and more particularly, further sharing of content messages, emotions, feelings, wellbeing, states of mind, general interest, marketing and advertising, and interactive behavior for likeminded people.

Digital badges need a form of universal standard language which would transcend normal language and enhance it for the digital communication between at least two badges or at least between badge and receiver. The communication protocol would also need to take this language into account to enable humans to act on the language interaction. Conventionally, people cannot transmit a message directly to another person who is in their line of sight without talking, signaling or using a facial expression to communicate with them. There is currently no method for a person to send an electronic signal to person in their line of sight directly. There is currently no method for an individual to display and instantly transmit their willingness to be approached, feelings, emotions, state of mind, state of like-mindedness, social media footprint, general interests and digital information or online dashboards. Furthermore, there is no global standard or universal symbol language to communicate non-verbal approach messages via badge devices. Currently, there is also no way for two like-minded people to share non-verbal content messages between badges and, or static devices.

In the midst of the Coronavirus pandemic gripping the entire world, it has become increasingly clear that a line-of-sight signaling devise may be crucial for signaling to others a “health status”. This displayed “health status” would ensure an “up-to-the-minute” digital certification issued by a public health registry—allaying any concerns or fears from others attempting to engage. This “health status” display would allow for even non-essential channels of commerce to reopen. It has been recently estimated by the IMF that we will experience a 3% contraction in global GDP as a result of the pandemic. The sectors that have been most affected are those that involve a high-level of social interaction, such as the food service industry. According to a recent report from the National Restaurant Association, 3% of the 4,000 member restaurants have already permanently gone out of business, with a staggering 12% anticipating going out of business by the end of April 2020. This vital channel of commerce may be reopened—despite the lack of ubiquitous testing or a vaccine—provided every customer and employee was mandated to display a time-stamped public health agency-issued “COVID-free” certification.

Furthermore, there is sorely a need for a user-worn display device that may also be used as a social distancing and contact tracing tool. While there is an emerging consensus that social distancing has been instrumental in flattening the epidemiological curve, in reality, it is quite difficult to constantly practice, especially in more dense cities, such as New York City. Practicing social distancing in heavily foot-trafficked scenarios would be significantly easier with a device triggering a color, symbol, or audio alert upon detecting the presence of another device within a threshold proximity. Moreover, this registered contact could be tracked for facilitating future contact tracing efforts. While there are a number of apps designed to track contact for tracing purposes (TraceTogether), the contact registered is not made known to the individuals involved at the time of contact. The extant systems are mobile device-based and do not feature a line-of-sight display alerting individuals of the contact at the time of the contact. Without a line-of-sight real-time alert, individuals may be prone to unwittingly extending the contact, thereby further exposing oneself to an infection.

In addition, there is a lack of a standardized certification or certification signaling display on a user-worn device (circle-of-sight or line-of-sight wearable device) or user-carried device (mobile device, a.k.a., cell phone or smart phone) to alert others (gate-keepers, business operators, event/venue participants) of a health-registry issued/validated certification of a negative virus infection test and/or a positive vaccination. Without a certification or certification signaling display, there will remain a lack of confidence or trust in family, social, or public gathering. Any effort to reinvigorate the decimated economy will require restoring confidence in lawmakers, public health experts, and the general public in gathering once again—whether in the once familiar confines of a loved one's home, at the neighborhood pizza shop or local bar, and in offices across the world. It is becoming increasingly evident that a health-registry issued certification display and/or certification signaling display on a user-worn or carried device is mission-critical.

Furthermore, there is a void for a digital health credentialing system that is ‘off-grid’ and does not rely on accessing a centralized health database or registry for validating a health status. There is a need for real-time validation of a venue-seeker by a gate-keeper or authority to ensure safety of other patrons in a crowded venue/event.

SUMMARY

The non-verbal line of sight electronic communication protocol (NVP) described herein allows the viewer to instantly understand the symbol and, or color-coded display cues of the interactive badge and understand whether the individual displaying the visual cues can be: (1) approached and (2) whether an information exchange can take place immediately or in the future. It also allows the user to send and receive information that could not previously be exchanged through normal human communication means.

Generally, the non-verbal line of sight electronic communication protocol (NVP) includes a standardized set of symbols, colors, and electronic communication protocol standards that enhance human communication to a new level. The NVP allows individuals to create new human behaviors and send messages beyond the natural 5 senses. The NVP allows individuals to build their own window of their life, display it on a personal digital display, and then have others interact with them. The NVP allows individuals to ‘think’ by creating their life window, ‘act’ by uploading to their personal digital display, and ‘do’ by using the interactive communication protocol.

The NVP allows communication between humans to take place while in their line of sight over and above their normal senses. The NVP can be implemented on any personal digital display that is running the NVP protocol. This protocol allows a signal to be passed between NVP devices only when certain combination of symbols and colors are displayed. This communication can trigger the transfer of information from one individual to another. Preferably, this NVP interaction guided by the standardized set of symbols and, or colors may be displayed on a center and, or surround visual display of an interactive badge worn by a first user, and in the line of sight by at least a second user.

It is one object of the invention to disclose a non-verbal line of sight electronic communication (NVP) system, comprising an interactive badge device with a line of sight device visual display. The device visual display being at least one of a surround device display and, or a center device display. Additionally, the device may have an interface module housed within the interactive badge device and configured for causing an event state change between at least one of a mobile device, surround device display and, or center device display. Moreover, the system may have a processor; a non-transitory storage element coupled to the processor; and encoded instructions stored in the non-transitory storage element, wherein the encoded instructions when implemented by the processor, configure the system to: (1) upload NVP interaction rules and curated NVP content for display on any one of a first user's device based on the first user's interaction rules and scheduler criteria; (2) send at least one of an interaction and, or content message based on the first user's interaction rules and scheduler criteria to at least one of a second user's device within range and contingent on the second user's interaction rules; and (3) based on the second user's interaction rules, accept or deny the first user interaction message, and if accepted, decode a unique tag to trigger a unique digital event, wherein the digital event may be at least one of an image, video, sound, vibration, flash, signal, symbol, color, text, upload, sequence, download on any one of the user's device visual display, and, or over a network.

It is another object of the invention to disclose a non-verbal line of sight electronic communication protocol. The communication protocol comprising a non-verbal symbol language for communicating wirelessly over electronic devices, including interactive badges and, or displays, between users and, or static receivers, who are in one another's line of sight; and the symbol language displayed on the interactive badge and, or display and, or static receivers communicate whether a first user can approach at least a second user or not for further digital interaction.

It is yet another object of the invention to provide for a device-centric, non-verbal line of sight electronic communication protocol. The device-centric, non-verbal line of sight electronic communication protocol comprising a non-verbal symbol language for communicating wirelessly over electronic devices, including an interactive badge with a line of sight device visual display, between users who are in one another's line of sight. The symbol language further comprising a set of any shaped and, or colored symbols that are programmably displayed on the device visual display, wherein the device visual display is at least one of a surround device display and, or a center device display. Furthermore, based on the programmably displayed set of shaped and, or colored symbols on the device visual display, communicate whether a first user can approach at least a second user or not for further digital interaction.

Aspects and advantages of this invention may be realized in other applications, aside from the intended application of interactive badge device-mediated communication and a communication protocol thereof. Other pertinent applications that may exploit the aspects and advantages of this invention are: digital advertising and digital commerce platforms integrated into the NVP communication system and protocol. For instance, an activity footprint of a user's displayed NVP content and, or replicated digital or virtual NVP content may be tracked for advertisers to target the most influential users for a brand display-for-hire. Moreover, a plurality of advertisers may bid for the most influential user's using a bidding module within the advertising platform, creating upward pressure on the brand display-for-hire fees. What's more, tracking of a user's NVP line of content displayed or virtually replicated, may enable a commerce platform or participants of the platform to push suggested digital content that is personalized to the user based on the user's running NVP content. Yet another digital event that may be triggered: may be the interaction of the badge device with other badge devices or fixed access devices near access-gates, wherein the symbol and, or color-coded display on badge or fixed-access devices invite for approach; once approached and interacted with, uploading an authentication tag over a network to a remote server; validating the authentication tag against a library of authenticated tags; downloading the validated tag and using the symbol and color-coded display on the badge device or fixed-access device to communicate permission to access. Additional digital events may include enabling the same interactive badge devices or fixed-access devices to process payment transactions, over a network, via an intermediary payment system.

In another aspect, a system, method, and device for a line-of-sight user-worn digital badge device for health certification and distancing display is disclosed. The system may comprise a first user-worn display device; a first user-networked device; said first user-worn display device housing an interface to communicate with the first user-networked device and at least a second user-worn display device; said first user-worn display device comprising at least one of a front or side wall with a visual display, wherein said visual display is in a line of sight of at least a second user while worn by a first user; a key unique to any one of the user-worn display device for decrypting an encrypted health token from a public heath server via a network to the at least first user-networked device for displaying a “clean” health certification in a form of a color and/or symbol code on the at least first user-worn display device; a processor, non-transitory storage element coupled to the processor, and encoded instructions stored in the non-transitory storage element, wherein the encoded instructions when implemented by the processor, configure the system to: upload decrypted health token from the at least first user-networked device for displaying the “clean” health certification in a form of a color, symbol, and/or audio-code on the at least first user-worn display device; and upload pre-defined distancing rules from the at least first user-networked device for display on the at least first user-worn display device of at least one of color/symbol/audio-coded warning of registering presence of at least the second user-worn display device within a threshold distance of the first user-worn display device based on the pre-defined distancing rule.

In another aspect, provided is a system and method for a user-worn or carried device certification display—enabling a second user to view the results of a virus test and/or a vaccination in order to allow entry of the first user wearing or carrying the device into the event or venue. The results may be presented in the same form as the health-registry issued test/certification or it may be presented in a standardized color or symbol-coded fashion based on a pre-defined protocol for quick-capture/assessment. Optionally, each event/venue operator (gate-keeper) may define the protocol unique to their event or venue, while blind to others (including the user) in an attempt to maintain medical privacy (single-blind certification signaling display). In other aspects, the gate-keeper may be disposed with a point-of-entry (P.O.E) terminal (or P.O.E app on gate-keepers device) for scanning or digitally interacting with the users worn/carried device for certification/signaling display on the gate-keepers P.O.E terminal display/device display.

It is another object to provide a system and method for a gate-keeper to digitally validate a venue-seekers health credentials in real-time by strictly relying on a color/symbol/audio-coded display based on a detection of magnetic nanoparticle carriers of a therapeutic/vaccine (therapeutics/vaccine delivered via magnetofection). The magnetic nanoparticles are made of iron oxide or any other superparamagnetic nanoparticle, which is fully biodegradable, coated with specific non-viral vectors, and optionally, cationic agents depending upon the applications. Their association with the gene vectors (DNA, siRNA, ODN, virus, etc.) is achieved by salt-induced colloidal aggregation and electrostatic interaction. The magnetic particles are then concentrated on the target cells by the influence of an external magnetic field generated by magnets. These same magnetic properties may be exploited for a real-time visualization of a users health credential.

In one aspect, a method for displaying a health status on a user-worn or carried device comprises the steps: disposing a magnet within a housing of the user-worn or carried device, configured to detect a magnetic field supercutaneously, wherein said field is generated by an interaction of the magnet with magnetic nanoparticles of a delivery agent delivering a therapeutic or vaccine intravenously; converting the detected magnetic field into a field-specific electrical signal; and outputting at least one of a pre-defined color, symbol, or audio-coded display on a display portion of the user-worn or carried device signaling the user health status based on the converted field-specific electrical signal.

Other aspects and advantages of the invention will be apparent from the following description and the appended claims.

The appearances of the phrase “in one embodiment” in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Moreover, various features are described which may be exhibited by some embodiments and not by others. Similarly, various requirements are described which may be requirements for some embodiments but not other embodiments.

Overview:

The present disclosure relates to a new non-verbal language that has been developed for the emerging electronic line of sight badge communication. The language will be referred to in the document as NVP which an abbreviation of Non Verbal person to person line of sight communication protocol standard. NVP is both a language and a communication protocol and this document initially describes both and then gives examples of how this is programmed and then examples or actual uses in the identified markets.

Exemplary Environment:

Now in reference to FIG. 1. FIG. 1 illustrates an exemplary system environment 100 in which various embodiments of the non-verbal line of sight communication protocol system (NVP) can be practiced. In accordance with an exemplary embodiment, the NVP system 100 comprises: an interactive badge device 101 a, 101 b with a line of sight device visual display; the device visual display being at least one of a surround device display and, or a center device display; a processor; a non-transitory storage element coupled to the processor; encoded instructions stored in the non-transitory storage element, wherein the encoded instructions when implemented by the processor, configure the system 100 to: upload NVP interaction rules and curated NVP content for display on any one of a first user's interactive badge device 101 a based on the first user's interaction rules and scheduler criteria; send at least one of an interaction and, or content message based on the first user's interaction rules and scheduler criteria to at least one of a second user's interactive badge device 101 b within range and contingent on the second user's interaction rules; and based on the second user's interaction rules, accept or deny the first user interaction message, and if accepted, decode a unique tag to trigger a unique digital event, wherein the digital event may be at least one of an image, video, sound, vibration, flash, signal, symbol, color, text, sequence, upload, download on any one of the user's device visual display and, or over a network.

The network 103 may be any suitable wired network, wireless network, a combination of these or any other conventional network, without limiting the scope of the present invention. Few examples may include a LAN or wireless LAN connection, an Internet connection, a point-to-point connection, or other network connection and combinations thereof. The network 103 may be any other type of network that is capable of transmitting or receiving data to/from host computers, personal devices, telephones, video/image capturing devices, video/image servers, or any other electronic devices. Further, the network 103 is capable of transmitting/sending data between the mentioned devices. Additionally, the network 103 may be a local, regional, or global communication network, for example, an enterprise telecommunication network, the Internet, a global mobile communication network, or any combination of similar networks. The network 103 may be a combination of an enterprise network (or the Internet) and a cellular network, in which case, suitable systems and methods are employed to seamlessly communicate between the two networks. In such cases, a mobile switching gateway may be utilized to communicate with a computer network gateway to pass data between the two networks. The network 103 may include any software, hardware, or computer applications that can provide a medium to exchange signals or data in any of the formats known in the art, related art, or developed later.

In a preferred embodiment, the line of sight interactive digital badge device (badge device) 101 a, 101 b is worn on one or more body parts of the user, such as chest, wrist, waist, neck, arm, leg, abdomen, thigh, head, etc. Further, the badge device 101 a, 101 b may be a wristband, a watch, an armband, a necklace, a headband, an earring, a waist belt and, or a ring. Alternatively, the badge device may be any reconfigurable display that may be temporarily or permanently affixed onto a garment of a user. In yet other alternative embodiments, the reconfigurable display may be a flexible OLED tube or screen interwoven into the fabric of the garment. Badge devices 101 a, 101 b may have a device visual display that is situated in any one of a person's line of sight. The device visual display may be a single center display, wherein the symbol and, or color-coded visual display cueing a permission to approach and further interact is displayed on the single, center visual display. The same single, center visual display may also display the NVP content. The same display may also be enabled for touch-screen interactivity. In other embodiments, interaction with the display contents may be controlled by controls disposed on a side, top, or bottom wall of a (circular or square) device casing. In yet other embodiments, the device visual display may be comprised of a dual display: a center device display and a surround device display. Each display sharing display functions or having unique display functions. For instance, in some embodiments, the surround device display may display the symbol and, or color-coded visual cues encoding for a permission to approach and interact, while the center device display may strictly display the actual NVP content (a static or a rolling line of user-content images).

In some embodiments of the badge device 101 a, 101 b, sensors may be disposed within the (domed) device housing, or on the (circular or square) device casing, to capture at least one of a user environmental or contextual data to further inform a user mood, emotion, physical condition, mental well-being, and, or willingness to be approached by other digital badge users for further interaction. The digital badge device 101 a, 101 b is first sent to the mobile communication device 102 and thereby, sent to the processing unit over the network 103. The digital badge device 101 a, 101 b communicates with the mobile communication device 102 over a short-range wireless communication medium., such as Bluetooth, etc. In other embodiments, sensor input may be derived from devices other than the badge device 101 a, 101 b. Device input may also encompass the sensor-captured raw data input or transduced and processed data input from any other device associated with the user, such as devices worn, mobile devices, and, or fixed-access devices, such as Internet-of-Things devices (e.g. smart thermostat, home automation consoles, etc.). The plurality of device inputs provides additional input for aggregation and behavior profiling, thus layering the behavior profile with additional context for generating a higher fidelity of user mood, emotion, well-being, etc. This higher resolution of user profiling may update the user interaction rules and, or policy for determining access for approach and activating further digital event/content interaction.

In continuing reference to FIG. 1 and the exemplary environment of the NVP system, a mobile communication device 102, such as a smart phone, is a portable device that has the capability of communicating over the network 103, presenting dashboard provisioning based on a respective digital badge device 101 a, 101 b pairing. Examples of the mobile communication device 102 include, but are not limited to, a smartphone, a tablet, a personal digital assistant (PDA) and a mobile phone. The mobile communication device 102 may be paired with a respective digital badge device 101 a, 101 b over a short-range wireless communication medium.

Examples of the short-range wireless communication medium include Bluetooth, ZigBee, Infrared, Near Field Communication (NFC) and, or Radio-frequency identification (RFID). Likewise, the digital badge device 101 a, 101 b may interact with other digital badge devices 101 a, 101 b using a short-range communication protocol, such as Infrared, Bluetooth, ZigBee, NFC, and, or RFID.

Preferred embodiments may include the addition of a remote server 105 or cloud server to further provide for back-end functionality and support. The server 105 may be situated adjacent or remotely from the system 100 and connected to each system 100 via a communication network 103. In one embodiment, the server 105 may be used to support user behavior profiling; user history function; predictive learning/analytics; alert function; network sharing function; digital footprint tracking; e-commerce/advertising platform support, etc. The remote server 105 may be further configured to authenticate the user and retrieve data of the user, device, and, or network and applies the data against a library of validated user information for enabling a payment or ticket transaction at a fixed-access point deploying an embodiment of the interactive badge device 101 a, 101 b.

Now in reference to FIGS. 2 and 3. FIGS. 2 and 3 both illustrate an exemplary embodiment of the NVP system. FIGS. 2 and 3 illustrate an exemplary processing unit 202 g, 302 g used for displaying a visual cue for permission to approach and, or a content display for exchange between interactive badge devices 201 a, 201 b or sharing over a network 203. As shown, the processing unit 202 g, 302 g may be communicatively coupled to at least one of an interface module 202 a, display module 202 b, input module 202 c, replicate module 202 d, a logic module 202 e, a context module 202 f, an interface module, a timeline module, a tracking module, 10 an advertising module, a notification module, and a commerce module. The processor 202 g, 302 g may also communicatively coupled to a remote database 205, 305 and a memory 202 h, 302 h 1 n an embodiment of the present invention, the processor 202 g, 302 g includes a notification/alerting module. The notification/alerting module is configured to generate reports at regular intervals (such as daily at 12:00 PM, weekly and monthly), on-demand (when the user requests for a report corresponding to the user), or when triggered by a digital event. Typically, a digital event may be defined as any digital display for badge-badge display or network sharing or server authentication. The notification/alerting module may double up as a tracking module, wherein a user may keep track of his or her physical displays and interactions, as well as his or her virtual displays and interactions.

In an embodiment of the present invention, the notification/alerting module may also be configured to send a notification to the user of the growing social influence of a user. In other words, an influence metric may be pushed quantifying how many people I have interacted with, and how many times my virtual NVP line of content been shared with other users on social media. The notification may be a message, a phone call or any other communication means.

In an embodiment of the present invention, the processor 202 g, 302 g includes a timeline module. The NVP line of content may be displayed or pushed in at least one of a static, dynamic, and, or scheduled fashion on at least one of the user's center device display based on at least one of the user's scheduler criteria. The line of static, dynamic, and, or scheduled images and, or video NVP content from at least one of the user's to be displayed on at least one of the user's center device display may be curated by the user, pre-set, or dynamically pushed based on any one of user parameter. In some embodiments, the timeline module enables the displayed line of static, dynamic, and, or scheduled images and, or video NVP content to be further replicated on at least one of a digital and, or virtual presence of at least one the users. In other words, the timeline module enables the displayed line of NVP content to be further shared with social media and digital media outlets, over a network. In some embodiments, an Application Programming Interface may be integrated and configured for enabling transfer and, or further interaction of the replicated line of static, dynamic, and, or scheduled images and, or video NVP content.

The processor 202 g, 302 g may include an advertising module and, or a commerce module, enabling advertisers to target users for NVP content display based on NVP activity or influence of said users. The advertising module may further comprise a bidding module, wherein the advertisers bid among each other for engaging a user for incorporating a winning bid advertisement into the NVP content display of the user. The processor 202 g, 302 g may further comprise a commerce module, wherein users may purchase digital downloads of NVP content for NVP content display. The commerce module may further be coupled to a distributive digital ledger, wherein each NVP exchange among any user is represented as a unique node in the digital ledger. Each node tagged with meta data facilitating at least one of a transaction, validation and, or registration for each NVP exchange.

In some embodiments, any one of the processor functioning mentioned above may be off-loaded to the processor of the mobile device and, or the remote server. The device display may simply be used for display function—for both symbol and color-coded display cues on any one of the surround display and, or center display, and NVP line of content on the center display.

The NVP language is made up of symbols, shapes, colors and images that when combined form a language specifically for the person to person or groups of people interactive badge or screen market. This language is the only language that allows individuals to communicate with the interactive badge in a visual sense. The NVP may be displayed on a surrounding of the interactive badge device and, or on device center display. In some embodiments, the surround display and center display may be combined in unison, or in a sequential manner, to express the NVP language.

The NVP Language Components

The first component of the language is a shape such as but not limited to a square, circle, triangle or star. These shapes indicate to the viewer a behavioral welcoming state of the person viewing them. One such behavioral state might be a welcome to communicate or not as the case might be. An example of these shapes and their uses are shown in FIG. 4. This first component forms the frame of all the communication symbols to follow. It is programmed by the NVP wearer at the start of a badges or screen or display wearing session.

The second component of the NVP is the color of the first component. This color signifies the rules of communication and engagement with the wearer and the receiver. The color signifies whether a person is willing to accept a communication and what type of communication from the viewer. The color can be part of the symbol or a color displayed on or around the badge An example of this is shown in FIG. 5.

The third component of the NVP is the symbol within the colored shape. These symbols can be anything which conveys a message to the viewer from the wearer but can only be shown using the NVP programming protocol described later. These symbols can be programed to be shown for a certain amount of time using the NVP programming software scheduler and these symbols can also flash based on that scheduler. These symbols can be different colors based on the person's mood. Some examples of the symbols for NVP are shown in FIG. 6.

In a preferred embodiment, disclosed is a non-verbal line of sight electronic communication protocol, the protocol comprising a non-verbal symbol language for communicating wirelessly over electronic devices, including interactive badges and, or displays, between users and, or static receivers, who are in one another's line of sight; and the symbol language displayed on the interactive badge and, or display and, or static receivers communicate whether a first user can approach at least a second user or not for further digital interaction.

For instance, the interactive badge or display that is displaying a blue square 402, 502, 602, which indicates that it's ok to approach me. Inside of which a green square 606 indicates its ok to talk to me and send me a NVP communication and a lonely face 610 from the symbols show that I am lonely. This symbol is programmed to the badge using the NVP programming language software which allows for timing and scheduling. The color of the symbol is the open or closed gateway to the receiver. If the color is not correct the communication will not pass. Alternatively, in other embodiments, any combination of shapes and, or colors may be arbitrarily chosen to signify a permission to approach or activate a further digital content interaction. For instance, a green circle might suggest permission to approach, and a blue square contained therein may suggest a permission to exchange an NVP line of content. Choice of colors, symbols, and the interaction with each, may be purely arbitrary.

The NVP Programming Interface

To allow a wearer to program their interactive badge or personal digital display, a programming interface is required which allows the wearer to set up the language on the badge and run it throughout a day as a timeline. This requires a process which is described in detail in FIG. 7. In a preferred embodiment of the process, the wearer decides to program the badge or display with the NVP language; the program which runs on the connected device (smartphone or 10 PC) is opened and the language variables are displayed; the NVP language components 1, 2 and 3 can be selected; the ability to send a communication to another wearer can be selected; and the ability to send the entre NVP wearers timeline can be selected. Additionally, the NVP program allows the wearer to select images from their own images, from the NVP store, feeds from interfaces with social media applications, from adverts selected from the NVP advertising platform, from health devices, from games, music and programming from a specific GPS location. Additionally, the amount of time an image is displayed may be programmed with the resulting timeline transmitted from the device to the wearable badge (FIG. 8). The process for setting the rules of interaction and engagement is further set out in FIG. 9. Once the NVP time line is set, this is transmitted to the badge and can be altered in real time. An example of this in vertical format is shown in FIG. 10. Alternatively, the line of NVP content may be depicted or scrolled in a horizontal fashion.

The NVP Communication Protocol Standard

As illustrated in FIG. 11, the NVP communication system allows one individual who is wearing an interactive badge or screen—in the line of sight of another individual wearing the same—to send messages wirelessly based on the NVP displayed. The message can only be sent if the NVP is set to the correct parameters set out in the NVP language section of this document. The NVP protocol has a unique number attached which allows the receiving interactive badge or screen to decode it and activate an event such as but not limited to an image display, a sound played, a vibration, or a signal sent back to the sender or a signal being sent to the parent smartphone, which in turn activates an event.

This NVP signal is defined as a unique wireless signal sent from one interactive badge or screen to another over a certain physical distance in line of sight. Using the NVP signal, the interactive badge can send an NVP signal to any number of badges or receivers and the badge can accept an NVP signal from any number of badges. The NVP signal can only be accepted if the correct NVP symbols are being displayed. By accepting an NVP signal this can trigger the interactive badge or screen to display anything it's been programmed to by the NVP app running on the smartphone or PC. If accepting the NVP signal this can trigger a sound or vibration or cause a device to trigger a sound or device. On accepting the NVP signal this can trigger the NVP app running on the smartphone to activate an event or process. On accepting the NVP signal, this can trigger the interactive badge or screen via the NVP app to display a set of offers, images, videos or sounds.

In a preferred embodiment, a non-verbal line of sight electronic communication protocol is disclosed, the protocol comprising: a non-verbal symbol language for communicating wirelessly over electronic devices, including an interactive badge with a line of sight device visual display, between users who are in one another's line of sight; the symbol language further comprising a set of any shaped and, or colored symbols that are programmably displayed on the device visual display, wherein the device visual display is at least one of a surround device display and, or a center device display; and based on the programmably displayed set of shaped and, or colored symbols on the device visual display, communicate whether a first user can approach at least a second user or not for further digital interaction.

The technology used to send and receive the NVP signal can be at a specific frequency with a unique number. This has the effect of making any other device not able to recognize the NVP signal or be able to manage the events that have been set by parameters with in the App. This unique number and encryption method makes the NVP interactive badge or screen only recognizable with another NVP interactive badge or screen or receiver or a licensed piece of hardware and software from the NVP group of products. This will be a critical area of protection for the NVP language and protocol—as without it—other manufacturers will not be able to enter the market as people will not be able to interact with their badge. The NVP language is the standard for interactive badges and devices. In short, the NVP signal can be a visual equivalent of a click through.

The Virtual NVP line

FIG. 12 illustrates the transition from badge 1 display; share with badge 2; and digital media share of badge 1 display with tracked footprint (badge 2 share). Virtual NVP is the digital version of the visual NVP line shown on the interactive badge or screen that can be made available to NVP badge users so they can see what others are displaying on their NVP badges that day. There are two uses for the Virtual NVP line: 1) to allow NVP badge wearers to transmit their NVP line from one user to another; and 2) to allow NVP badge wearer to attached their own.

The pre-defined presentation of the content message on at least the interactive device visual display and, or virtual profile may be configured for network or digital sharing. Furthermore, the virtual profile may, via an Application Programming Interface, be configured for transfer and, or further interaction—such as geo-location, site check-in, etc. In other embodiments, the NVP system has been developed so there is a very low entry point for integration to the program. In fact, as the user is only taking a screen shot of their phone for any media there is no integration with 3rd parties necessary. By way of an example, a user could construct a NVP line of their Facebook post, Twitter post, dashboard from Fitbit, images from their phone and a mood image. All of these can be taken directly from screenshots with no outside integration from developers needed. These screen shots can be real time based on the time of NVP line creation.

In some embodiments, live data feeds from monitoring devices would be image related, so rather than display on the device, a mirroring program would allow the device display to be shown on the NVP badge via Bluetooth. This NVP ‘Llego’ block is a universal interface to all monitoring and real time feed devices.

As each person is responsible for their own NVP line they are responsible for the content that is published. However, the NVP system has a safe guard to ensure that inappropriate and copyright content is not displayed. Each time an NVP line is created it must pass through the NVP ‘Llego’ Block server to pick up any illegal images. If this happens, the NVP line will be rejected and the user asked to review the images. The NVP ‘Llego’ block interface allows media channels to display their content on the NVP badge if the user so wishes. These channels are passed through the NVP Llego block centrally and are available for users to connect to if they so wish using the NVP line creation software. There are many markets for the NVP interactive language and its communication protocol. The application that follow are just some examples

Application 1: Advertising Targeting

The groups are based not on where you are digitally i.e. Facebook or Twitter but where you are physically i.e. on a train, at a concert, at a bar or at work. We will be able to count how many NVP signals were sent to individuals and what they reacted to. In this way new physical influencers will emerge, i.e. those who are the most popular. These peoples virtual NVP lines will be the most desirable from an advertising perspective as they will enhance their online profile with that running on their interactive badges or screens. The diagram in FIG. 14 shows what might typically happen to a person wearing and actively using the NVP language on a daily basis.

As illustrated in FIG. 13, girl A has collected 43 NVP signals and had 16 conversations about the NVP line she is displaying. If she has configured her NVP line correctly each person who has sent an NVP signal will have received her Virtual NVP Line. which was reacted to. Note that girl A had configured two NVP lines for different parts of her day. So different people will see different NVP line. What is clear is that as the NVP language and communication protocol becomes established the number of transactions will grow exponentially as each of the above people will have their own NVP badge and their own NVP line We will quickly see the emergence of the top real life influencer in a daily basis. Advertisers will be able to target the most popular real time influencers based on NVP sharing activity.

In other embodiments, the advertising module or platform may further comprise a bidding module, wherein the advertisers bid among each other for engaging a user for incorporating a winning bid advertisement into the content message display of the user. Advertisers will be able to use the NVP Real Time Bidding Network to get access to the NVP line of targeted individuals if they have given their consent to take advertising in their NVP Line. These adverts will be clickable on the Virtual NVP line so they can be transferred from one user to many in the Real Life Network®. This potentially gives advertisers a major new network of people to target based on their location.

Application 2: The NVP Store or Shop Controlling the NVP Content

Images will be able to be taken from a person's phone and shown on the NVP badge. As these are put onto the NVP line through the NVP App, we have control over the content and can manage any indecent, or inflammatory content. However, the final say will be with the NVP badge wearer. We will have complete control over the Virtual NVP line and be able to stop the distribution of any indecent or inflammatory content. Additionally, there will be a place to purchase widgets that link directly to apps such as Facebook, Twitter and other apps that have integrated with our NVP Llego Block. Brands, Apps and advertiser will have to pay to be allowed on the portal and be subject to our terms and conditions. We expect this fee to be a % of any purchase price or a fixed fee based on an individual's use. i.e. if the wearer wants to buy a specific logo or album cover, they can buy this for a one-off fee from the supplier. We would retain 10% of the retail revenue. This logo would be allowed to be used on the individuals NVP badge, but not be transferrable to another person NVP Line via the virtual NVP line which is read only.

The payment transaction system may incorporate block chain technology, wherein each NVP exchange or digital content purchase transaction among any user is represented as a unique node in the digital ledger, each node tagged with meta data facilitating at least one of a transaction, validation and, or registration for each NVP exchange or digital content purchase transaction. Alternate payment systems may be used, including linking directly to a credit card, debit card, and, or bank account. In yet other embodiments, payment systems may include an intermediary or 3rd party system providing payment processing between users or between user and the NVP store. An intermediary account or escrow-type account may also be used, whereby funds are disbursed from a user 1 account to a user 2 account, or from a user 1-linked intermediary account to a user 2 account—upon full satisfaction of transaction or bidding obligations. The intermediary account may be viewed as a pre-paid account. In other embodiments, digital sellers may target users who have pre-paid an intermediary account for a specific item, thereby competing over a particular purchaser for a specific items.

Moreover, in some embodiments, the NVP communication protocol standard may be incorporated into the payment transaction system coupled to the commerce platform or NVP store. For instance, a yellow square on the surround display or center display of the interactive badge may signify that the user is willing to purchase a digital content for download or a physical item. In other embodiments, the yellow square displayed may signify that after scanning a physical item tag, the user's account or intermediary account has a sufficient balance to afford the item. Contrastingly, a red square may indicate that the item may not be purchased based on available balance. In yet other embodiments, a green circle may signify that a payment transaction is confirmed.

To run through a potential scenario, two individuals have bought an interactive badge which runs the NVP language, communication protocol and programming language. Each one has programmed their badges to run a 6-image timeline changing every 30 seconds. They both are on a train in the morning and find themselves sitting opposite one another. Individual 1 sees that individual 2 has a green square framing their timeline of images and knows that this signifies that the person is open to a conversation, is open to receiving an NVP signal and is open to receiving a virtual NVP timeline from this person. Individual 1 decides to send a NVP signal which causes the individual 2's badge to display a ‘Hi’, beep a sounds and flash once as this is standard for the NVP badge.

Individual 1 approaches Individual 2 and starts to discuss their images. Individual 1 also decides to send their virtual NVP timeline to individual 2. At the end of the day Individual 1 and 2 are able to read how many people have sent them a message, from whom and about what. This scenario can happen at any time of the day and the individuals can change the NVP components in real time through their App. Furthermore, individual 1 or 2 can purchase specific digital content from a coupled commerce platform to be displayed on their NVP line or virtual NVP. What's more, advertisers may target either individual 1 and, or 2 for advertising display based on individual 1 and, or 2's tracked activity.

Furthermore, a wide array of other user-initiated transactions may be enabled with use of the interactive badge device. The triggered digital event may further comprise at least one of an offer and acceptance of at least a credit, between at least two devices, redeemable towards at least one of a good or service with any one of a participating vendor. In other embodiments, the triggered digital event further comprises at least one of an offer and acceptance of at least a representation of a good or service, between at least two devices, redeemable towards at least one of a physical good or service associated with the representation from any one of a participating vendor. In other embodiments, the triggered digital event further comprises facilitating a payment transaction between at least one of a device-to-device, device-to-vendor POS terminal, or device-to-vendor product code.

The symbol language further comprises a set of any shaped and, or colored symbols that are displayed on the interactive badge and, or display or foldable display and, or static receivers communicate whether a first user can approach at least a second user or not for further digital interaction. The set of shaped and, or colored symbols that are displayed on the interactive badge and, or display and, or static receivers communicate whether a first user can authenticate the identity of the second user before sending a message. The set of shaped and, or colored symbols that are displayed on the interactive badge and, or display and, or static receivers communicate whether a first user can send a content message to at least a second user or not. Signaling multiple users in a vicinity may be possible, such as a battlefield, convention hall, restaurant, theater, public square, stadium, etc. Also, API-mediated third-party or on-board badge/mobile device sensor-driven contextual information (event type, venue type, weather, attendance, etc.) may factor into the distancing, contact tracing, and/or certification display on the badge device. Display may be on a badge device worn over a user garment in a line-of-sight of another user; badge device affixed to a back surface of a user mobile device; a foldable mobile device co-opted as a badge device with display on the outward-facing (facing another user) screen of the foldable phone. Additionally, an interactive eye-wear may be embedded with a symbol and/or light-display affixed on a frame of the eye-wear and/or lens surface. Much like the interactive badge device, the eye-wear will be paired to a mobile device and operably coupled to a health registry to serve as a public health tool by providing individuals with a line-of-sight distancing/certification display. What's more, a smart watch may be paired with a mobile device and operably coupled to the health registry for distancing/verification display—though not line-of-sight.

Now in reference to FIG. 14. FIG. 14 illustrates an exemplary system environment in which various embodiments of the distancing and certification line-of-sight device may be practiced. In accordance with an exemplary embodiment, the system may comprise: an interactive badge device with a line of sight device visual display; the device visual display being at least one of a surround device display and, or a center device display; a processor; a non-transitory storage element coupled to the processor; encoded instructions stored in the non-transitory storage element, wherein the encoded instructions when implemented by the processor, configure the system to: upload a decrypted health token from the at least first user-networked device for displaying the “clean” health certification in a form of a color and/or symbol code on the at least first user-worn display device 1402; and upload pre-defined distancing rules from the at least first user-networked device for display on the at least first user-worn display device 1402 of at least one of color/symbol/audio-coded warning of registering presence of at least a second user-worn display device 1404 within a threshold distance of the first user-worn display device 1402 based on the pre-defined distancing rule.

In some embodiments of the badge device 1402, 1404, sensors may be disposed within the device housing, or on the (circular or square) device casing, to capture at least one of a user environmental or contextual data to further inform a user-defined rule. The digital badge device 1402, 1404 communicates with the networked device (mobile communication device) 1410 over a short range wireless communication medium., such as Bluetooth, etc. In other embodiments, sensor input may be derived from devices other than the badge device 1402, 1404. Device input may also encompass the sensor-captured raw data input or transduced and processed data input from any other device associated with the user, such as devices worn, mobile devices, and, or fixed-access devices, such as Internet-of-Things devices (e.g. smart thermostat, home automation consoles, etc.). The plurality of device inputs provides additional input for aggregation and profiling, thus layering additional context for updates to the social distancing rules. For example, in compliance with Center for Disease and Control social distancing guidelines, as a general rule of thumb, people should remain six feet apart from one another. However, this distancing rule may be relaxed if people are engaged in outdoor activities, given the breeze and lack of touching surfaces. This may be especially true if said outdoor activity is jogging on a track, which may have a higher barrier of contagion, compared to waiting on-line in a grocery store, for instance, despite the fact that there may be several instances of being within a 6 foot proximity of a fellow jogger. In such instances, the distancing rule may take into account the activity of jogging by input from a fitness band and the fact that the user is jogging outdoors by a geo-location input or badge device sensor input.

While the badge device may be a line-of-sight, body-worn square/circular encasing or housing, any number of form factors may be used to network badge-badge or badge-mobile and perform distancing or certification signaling. While not shown, the badge device may be a wristband, a watch, an armband, a necklace, a headband, a mask, an earring, a waist belt, ring, foldable phone (fold-out/fold-down), detachable display, light or laser-projected onto a screen. Alternatively, the badge device may be any reconfigurable display that may be temporarily or permanently affixed onto a garment of a user. In yet other embodiments, the reconfigurable display may be a flexible OLED tube or screen interwoven into the fabric of the garment, such as a shirt, hat or mask. The symbol and, or color-coded visual display, serving as a vital public health tool by cueing to oneself and others a distancing warning and virus-free certification.

The network 1406 may be any other type of network that is capable of transmitting or receiving data to/from host computers, personal devices, telephones, video/image capturing devices, video/image servers, or any other electronic devices. The network 1406 may be a local, regional, or global communication network, for example, an enterprise telecommunication network, the Internet, a global mobile communication network, or any combination of similar networks. The network 1406 may be a combination of an enterprise network (or the Internet) and a cellular network, in which case, suitable systems and methods are employed to seamlessly communicate between the two networks in a safe manner without compromising sensitive data, such as patient. In such cases, a mobile switching gateway may be utilized to communicate with a computer network gateway of a public health registry to pass data safely between the two networks.

The mobile communication device or networked device 1406 may be paired with a respective digital badge device 1402, 1404 over a short range wireless communication medium. Examples of the short range wireless communication medium include Bluetooth, ZigBee, Infrared, Near Field Communication (NFC) and, or Radio-frequency identification (RFID). Likewise, the digital badge device 1402, 1404 may interact with other digital badge devices 101 a, 101 b using a short-range communication protocol, such as Infrared, Bluetooth, ZigBee, NFC, and, or RFID.

Preferred embodiments may include the addition of a remote server 1408 or cloud server to further provide for back-end functionality and support. The server 1408 may be situated adjacent or remotely from the system and connected to each system via a communication network 1406. In one embodiment, the server 1408 may be used to support user context (behavior profiling; user history function; predictive learning/analytics; alert function; network sharing function; digital footprint tracking; e-commerce/advertising platform support, etc.). The remote server 1408 may be further configured to authenticate the user and retrieve data of the user, device, and, or network and applies the data against a library of validated user information for enabling a payment or ticket transaction at a fixed-access point deploying an embodiment of the interactive badge device 1402, 1404. More vitally, the server 1408 may be a secured access gateway to sensitive and confidential patient medical data, which may need to be accessed for contact racing purposes or for decryption of a token for “virus-free” certification display.

Now in reference to FIGS. 15 and 17, which illustrate an exemplary distancing display schematic and legend, respectively. As shown in FIG. 15, in one embodiment, a first user badge device 1502 may comprise a circular or square housing with center display, further comprising an interface to communicate with a first user networked device and at least a second user badge device 1504. The housing may comprise at least one of a front or side wall with a visual display, wherein said visual display is in a line of sight of at least a second user and displays a symbol or color-coded communication of pre-defined distancing rules. In a preferred embodiment, the first user networked device recognizes the second user networked device within a rule-defined distance by any number of short-range communication. In addition to proximity, the rule may define for duration of contact, whereby only contact above a rule-defined time within proximity is displayed on the line-of-sight badge device display and registered on a public health registry; and contact below the rule-defined time within proximity is simply displayed. As shown in FIG. 17, a green square may indicate contact-free, while a red circle indicates extended contact registered. On the other hand, a red square may indicate a substantial amount of contact, albeit not beyond a pre-defined threshold of time, amounting to an extended contact. Finally, a yellow square may indicate a densely populated area, though no one within a pre-defined proximity to trigger a registered contact. It should be appreciated that the choice of colors and symbol are completely arbitrary. While not shown in FIG. 15, the badge device may be controlled by controls disposed on a side, top, or bottom wall of (circular or square) device casing. In yet other embodiments, the device visual display may be comprised of a dual display: a center device display (shown) and a surround device display, each with similar or unique display capabilities.

In other embodiments, the recognition of a contact-free or registered state may be processed by the line-of-sight badge device in short-range communication with the second user badge device, without pairing involvement from the networked devices. As shown in FIG. 14, the device processor has an interface module or circuitry for interfacing with the first user networked device, a second users badge device, a wider area network to a remote server for analytics and provisioning, or access to a public health registry. Also shown in FIG. 14, is a wide array of other processing capabilities that may be performed by the badge device alone, or in combination with the networked device—amounting to off-loading processing throughput from the networked device to the badge device.

In one embodiment, contact registering may further comprise (1) being within a wireless communication short-range of the at least second user-worn display device; (2) transmitting a signal with a tag to the at least second user-worn display device; (3) accepting the signal with the tag by the at least second user-worn display device; (4) decoding the tag by the at least second user-worn display device to trigger a digital event comprising at least one of a sound, vibration, flash, signal, symbol, color, text, curated line of static, dynamic or scheduled images or video content for display or download on the first and at least second user display device, or for upload over a network, wherein said digital event marks exceeding a threshold distance based on the pre-defined distancing rule.

The determination of contact and the extent of contact may be based on a signal strength of short-range communication. In other words, a signal recognized beyond a threshold strength may signify a threshold proximity. A threshold signal may be further characterized to fall within a spectrum of strength—corresponding to a spectrum of proximity; the weaker the threshold signal, the less substantial the registered contact. While it is not reflected in the legend illustrated in FIG. 17, a wider assortment of colors and symbols may be incorporated in order to reflect the extent of how substantial the registered contact is. Again, this may be distinguished from an extended contact (red circle FIG. 17), which is deduced from a time function—in addition to proximity—and is undoubtedly a more probative indicator of infection propensity.

Furthermore, inter-device interaction for achieving distancing display/warning may comprise a wireless signal sent from one user to at least one of a second user, group of users, venue entry (VE) terminal, Point-of-Health Certification (POHC) terminal, gate-keeper scanner, or static receivers, which transfers data based on the shaped and/or colored set of symbols displayed on at least one of a user's display device or static receivers. The data transferred may be primary information displayed on the badge device display in the form of color and/or symbols to convey a distancing or health status message. Alternatively, a secondary line of information may be displayed detailing time of registered contact information, date of health status certification issued from a health registry, duration of contact, extent of contact (at least one of substantial or non-substantial), etc.

In addition to contact alerting to ensure safe distancing, contact tracing is a critical public health tool for containing any infectious outbreak. Contact tracing is defined as the process of identification of persons who may have come into contact with an infected person (“contacts”) and subsequent collection of further information about these contacts. By tracing the contacts of infected individuals, testing them for infection, treating the infected and tracing their contacts in turn, public health may aim to reduce infections in the population. On a high level, there are three major levels to contact tracing: Contact identification, contact listing, and contact follow-up. Contact identification: Once someone is confirmed as infected with a virus, contacts are identified by asking about the person's activities and the activities and roles of the people around them since onset of illness. Contacts can be anyone who has been in contact with an infected person: family members, work colleagues, friends, or health care providers. Contact listing: All persons considered to have contact with the infected person should be listed as contacts. Efforts should be made to identify every listed contact and to inform them of their contact status, what it means, the actions that will follow, and the importance of receiving early care if they develop symptoms. Contacts should also be provided with information about prevention of the disease. In some cases, quarantine or isolation is required for high risk contacts, either at home, or in hospital. Contact follow-up: Regular follow-up should be conducted with all contacts to monitor for symptoms and test for signs of infection (World Health Organization). The exercise of Contact Listing may be exponentially expedited by having the badge device be in communication with a public health registry. The registry may keep a running tabulation of badge device identifiers, and for each badge device, a running list of registered contacts identified by badge device identifier.

As shown in FIG. 19, illustrating a contact tracing scheme in accordance with an aspect of the invention, the system and/or registry-maintained database keeps a running tab on registered contacts for user. It is organized in terms of time period, and the number of registered contacts during each time period in terms of their health status (A—Had infection, has antibodies; B—Infection-free; C—Not been tested; and D—Vaccinated). For instance, as illustrated in FIG. 19, user registered 13 contacts with individuals not yet tested during the course of his/her commute to work and up until lunch (C=5+C=1+C=7). Once a registered contact is confirmed positive for an infectious disease, he or she may be asked to voluntarily or mandatorily report the results to the public health registry, and the registry may communicate to all registered contacts of the infected that have been exposed and begin to prompt an isolation instructional. Beyond just communicating the fact that registered contacts of an infected may be exposed, other details may be provided, such as time of exposure and extent of exposure (contact, extended contact, extended contact grade 1, extended contact grade 2, substantial contact, substantial contact grade 1, substantial contact grade 2, etc.). This line of communication may be expressed in symbol and/or color code consistent with the legend displayed in FIG. 17. In one embodiment, the badge device system database and/or public health registry maintained database of user-worn display device identifiers with a real-time contact trail for each user (identified by an identifier) may be coupled to the at least first user device (mobile/badge) via a network for informing the entire contact trail of any user confirmed positive (self-reported or registry reported). Informing each user of the contact trail may further comprise at least one of the following information: date of contact with positively confirmed user; time of contact; location of contact; extent of contact, duration of contact; environmental information; or context of contact.

Now in reference to FIGS. 16 and 18, illustrating an exemplary certification display scheme and legend in accordance with an aspect of the invention, respectively. As shown in FIG. 16, the interactive, line-of-sight badge device may be communicatively coupled to a remote public health registry and decrypt/display a real-time “Covid-Free” certification (indicated by a green circle surrounded by a green square) for the user. This would allow “gate-keepers” of institutions to rest assure of the users admission. The user would have an option to opt-out of the “real-time” check and display a green circle surrounded by a red square—indicating a “Covid-Free” certification, albeit not real-time, though within a pre-defined period of time. As shown in FIG. 18, other potential display scenarios may be a green diamond indicating “Covid-Free”, however, untested within the last two weeks; a yellow circle indicating “Vaccinated” within the last 12 months; and a yellow diamond indicating “Vaccinated” outside of the 12 month window. It should be appreciated that any choice or combination of colors, shapes, and pre-defined windows of time may be used for the certification display. With that said, the selection will need to be universalized among users to convey an unambiguous signal to at least one of: Other users, fixed-access terminals (VE/POHC), or “gate-keepers”. In another potential exemplary display and interaction scheme: When the receiving users device reads these symbols or rules it changes the status of its own badge to reflect whether that person can enter a location or space around the badge. In another potential exemplary display legend: Antibody present in the user and not able infect—Safe—green square; Had the COVID 19 virus and therefore unlikely to be carrying—Safe—yellow Square; Not had the COVID 19 virus—warning—purple; Has the COVID 19 virus—Unsafe—red, or (A) Had infection; has antibodies (green square); (B) Infection-Free (green circle); (C) Not been tested; (D) Vaccinated.

Any number of color and symbol choices may be displayed for signaling at least one of the above four health status, vis-à-vis, a viral state (Covid-19, for instance). In addition to color and symbol language, any configuration of audio, flash, or vibrational alerts may be deployed on the user device (badge/mobile). The interactive nature of the badge is the most critical aspect of this public health tool. In some embodiments, if a badge comes within a distance of another, while displaying a noncompatible color/symbol, at least one of the two interacting badges may at least one of color/symbol display, flash, vibrate, or be audible. This alert output will serve three purposes: To inform others around of the status (clean/not clean) and permission to approach; to allow or block people interacting digitally with the user; and to allow (clean) user to enter physical locations.

In other embodiments, only similar (or compatible) signal display on each interactive badge device will trigger a further digital event. Digital events may be a transaction of any kind, information exchange, social media exchange, public heath registry requests/verification, etc. Conversely, dissimilar display between interactive badges will not trigger a digital event between badges/users.

Privacy of the users identity and sensitive medical information is of utmost importance. It is critical that the operably coupled badge device is not susceptible to security breaches—either at the device level, intermediary points, or public health registry level. Users may be masked by a badge identifier and test results may be packaged in encrypted packet/s (token). Each badge device may comprise a key unique to the badge identifier and token for downstream decryption and eventual display. This decryption/display pathway (as illustrated in FIGS. 20 and 21) is just one of many potential safe-packet-transfer mechanisms among any number of nodes in the network. In other embodiments, an enhanced packet transfer logic or other safe transfer enhancements may further be embedded in every node/network that further allows safe packet transfer between independent nodes without loss, corruption or denial-of-service related events. For instance, in some embodiments, a packet seal (cryptographic identifier) may be comprised within the packet. In other embodiments, safe transfer enhancements may include a public key identifier to locate and verify any sending or receiving node in any given transfer scheme. In another embodiment, a transfer scheme may further comprise the step of supplying a signed receipt of at least one of a successful packet receipt or transfer from at least a first node to at least a second node. The receipt comprising at least one of a public key or packet seal from a receiving node, combined with a cryptographic hash of the sending node. For instance, end node (user mobile device or interactive badge device) will supply signed receipt for encrypted packet (health status certification) received from public health registry, instead of just a success message. It's cryptographic hash of device identified token from the registry node combined with user device public key. This signature proves that the correctly requesting user device node successfully received the encrypted certificate for decryption and display and that it is in fact the correct end user device, defined by identifier, which received it.

In other embodiments, the unlocked/decrypted health certificate may be in a stealth mode, whereby the certificate is not line-of-sight displayed on the interactive badge device display, but rather, the certificate may be verified by a close-range interaction between “gate-keeper” interactive badge device and user badge/mobile device. Alternatively, the “gate-keeper” may close-range interact with the user device (badge/mobile) via an independent scanner operably coupled to a remote server (system/registry). In yet other embodiments, a badge device may be scanned by a VE/POHC fixed-access terminal for health status verification, despite not displaying a color/symbol code due to being in a “stealth” state.

FIG. 22 illustrates an exemplary method flow diagram for certification and distancing display on a user-worn badge device for infection prevention in accordance with an aspect of the invention. Step 1 entails: uploading a decrypted health token from the at least first user-networked device for displaying the “clean” health certification in a form of a color and/or symbol code on the at least first user-worn badge device 2202; and step 2 entails uploading a pre-defined distancing rules for displaying at least one of color/symbol/audio-coded warning of registering presence at least a second user-worn badge device within a threshold distance of the first user-worn badge device based on the pre-defined distancing rule 2204.

In other embodiments, the badge device exclusively deploys distancing waning/contact tracing, while not certifying a “clean” health status. The method for communicating pre-defined distancing rules on a user-worn badge display may comprise the steps of: programming a first badge device to alert upon recognizing another badge device based on a pre-defined rule, wherein the pre-defined rule factors at least one of: a wireless network strength, location, environment, activity, age of at least one of the users, pre-existing health of at least one of the users, or infection status of at least one of the users; and outputting an alert from at least the first badge device, wherein the alert is at least one of an audible output, flash, vibration, or color/symbol display.

In other embodiments, the badge device exclusively deploys a health status certification, while not deploying distance warning. The method for signaling a health registry-issued certificate on a user-worn badge display may comprise the steps of: coupling a user mobile device or badge device to a health registry for real-time decryption of a health registry-issued health certificate over a network; and outputting a color/symbol-coded display on the user badge device of a user health status based on the real-time decrypted health certificate.

FIG. 23 illustrates an exemplary method flow diagram detailing the steps entailed in achieving certification display in accordance with an aspect of the invention. In a preferred embodiment, a user-worn (Line-of-Sight or Circle-of-Sight) device or a user-carried (mobile device, a.k.a., smart phone) device serves to couple to a health-registry issuing virus test results or vaccination certification for decryption (or any other safe/discreet sensitive packet transfer method) and output of a color and/or symbol-coded display corresponding to the test results/vaccination status of the user based on a pre-defined protocol. The LoS device may be any one of badge, smart watch, locket housing a watch, eyewear, or clip-on element. The CoS device may be any one of an over-the-ear headphones, ear buds, paste-on stems, paste-on strips, or behind-the-ear clip-ons. The user-carried device may be a mobile device, a.k.a., cell phone or smart phone.

Shown in FIG. 23 is a method for outputting a health registry-issued test result or vaccination certification of a user on a user-worn or user-carried device, said method comprising the steps of: coupling the user-worn or user-carried device to a health registry for real-time decryption of a health registry-issued test result or vaccination certification for the user over a network 2302; and outputting at least one of a visual display or audible output from the user-worn or carried device certifying the user's test result or vaccination status based on the decrypted test result or vaccination status 2304. FIG. 24 illustrates the steps of: (1) coupling the user-worn or carried device to a health registry for downloading the test results or certification in its native format 2402; and (2) converting the native format into the color or symbol-coded output denoting the results or status of the user (signal format) 2404—bypassing the need for a decryption or any other safe/discreet packet transfer means. It is important to note that based on a pre-defined protocol, it may be that a negative test result and a positive vaccination are represented by the same color—green, for instance—but different symbols, or vice versa. Any color or symbol choice may be used to represent any test result or vaccination status based on a pre-defined protocol, operator/gate-keeper-defined protocol, etc.

In other embodiments, the test results or vaccination certification display in the native format is encrypted at the registry level and subsequently decrypted by a remote server in route to user device display, or alternatively, decrypted at the user device (mobile device) level. In other embodiments, an encryption/decryption combination occurs downstream of the registry—either at the server level or device level. In yet other embodiments, an encryption/decryption scheme is not necessary and a direct download from the registry to server and/or device may occur. Either encryption/decryption/download/display scheme may result in an outputting of the result or certificate in its native form, rather than in the converted signal form (color or symbol-coded display) as described above. Decryption or simply downloading (encoding) result/certificate in its native health registry-issued format may be initiated by the user or others (operator/gate-keeper). The native form display may be presented either in its unaltered form issued from the health registry, or may be in an abridged form (strictly salient information using text and/or numerals displayed), or an abbreviated form (strictly salient information in shortened text and/or numerals displayed). The abridged and abbreviated form allow for quick-capture of requisite information at a point of entry. FIG. 25 illustrates the native, abridged, or abbreviated form display of the test result or certification—rather than the color or symbol-coded conversion of the native format. As shown, the method entails the steps of: (1) coupling the user-mobile device to a health registry over a network for display of a health registry-issued vaccination certification for the user 2502; and (2) outputting a non-color or symbol-coded display from the user-mobile device certifying the user's vaccination status, wherein the non-color or symbol-coded display is at least one of a health registry-issued vaccination certification in its full (native) form, abridged form, or abbreviated form.

In other embodiments, either encryption/decryption/download/display scheme may result in simply an audio output from the user device (worn/carried) to infer or signal a test result or vaccination certificate corresponding to the user and based on a pre-defined protocol. A unique sound-mark may represent each test result/vaccination status—or similar sound marks may represent each of a different status. For instance, a short, high-pitched ‘ring’ may represent both a negative test result and a positive vaccination status; while a longer, lower-pitched ‘ring’ may represent both a positive test result and a negative vaccination status.

In other embodiments, either encryption/decryption/download/display scheme 2602 may result in a conversion into the non-color or symbol-coded display from the user-mobile device certifying the user's vaccination status, wherein the non-color or symbol-coded display is at least one of a health registry-issued vaccination certification in its full (native) form, abridged form, or abbreviated form (FIG. 26).

While not shown in FIGS. 23-26, the coded display may be either covert or single blind. The single blind display refers to an outward color or symbol-coded display that is only known to the particular business operator or gate-keeper due to a pre-defined protocol unique and only known to the operator or gate-keeper. This serves to maintain a level of medical information privacy for the user. In another effort to maintain privacy, the covert display feature is an outward display discernable by others in accordance with a pre-defined protocol, however, upon scanning/decoding, the color or symbol may appear different to the operator/gate-keeper, informing only the operator/gate-keeper of a potential fraudulent display. This may serve as a potent tool to prevent users from unlocking/decrypting health-registry packets for fraudulent display. Tag decoding may be done by a point-of-entry (POE) terminal or via the operator/gate-keeper device by any one of code scanning or device interaction/pairing.

Another fraud-prevention tool is a facial (or other distinguishing mark/feature) display to ensure proof of identity and rightful device. It is imagined that many may try to seek admission into an event or venue by using the device of others with permissible display. The facial display may appear as a separate dedicated frame, frame-within-result/certification frame, or split frame. It bears mentioning that an event or venue is any one of, but not limited to, an office space, mass transit, indoor eatery, arena, airplane, airport, train station, museum, movie theater, retail space, shopping mall, school, university, laboratory, grocery store, bar/pub, concert hall, etc.

Privacy of the users identity and sensitive medical information is of utmost importance. It is critical that the operably coupled certifying device is not susceptible to security breaches—either at the device level, intermediary points, or public health registry level. Users may be masked by a device identifier and test results may be packaged in encrypted packet/s (token). Each certifying device may comprise a key unique to the certifying device identifier and token for downstream decryption and eventual display. This decryption/display pathway (as illustrated in FIGS. 20 and 21) is just one of many potential safe-packet-transfer mechanisms among any number of nodes in the network. In other embodiments, an enhanced packet transfer logic or other safe transfer enhancements may further be embedded in every node/network that further allows safe packet transfer between independent nodes without loss, corruption or denial-of-service related events. For instance, in some embodiments, a packet seal (cryptographic identifier) may be comprised within the packet. In other embodiments, safe transfer enhancements may include a public key identifier to locate and verify any sending or receiving node in any given transfer scheme. In another embodiment, a transfer scheme may further comprise the step of supplying a signed receipt of at least one of a successful packet receipt or transfer from at least a first node to at least a second node. The receipt comprising at least one of a public key or packet seal from a receiving node, combined with a cryptographic hash of the sending node. For instance, end node (certifying device) will supply signed receipt for encrypted packet (health status certification) received from public health registry, instead of just a success message. It's cryptographic hash of device identified token from the registry node combined with user device public key. This signature proves that the correctly requesting user device node successfully received the encrypted certificate for decryption and display and that it is in fact the correct user and certifying device.

In other embodiments, either encryption/decryption/download/display scheme—whether on a user-worn or carried device—may result in a follow up digital interaction between user-worn or user-carried (U-W/C) devices. In this embodiment, the U-W/C device may also include for a gate-keeper point-of-entry terminal (fixed/portable) for a second layer of authentication/validation beyond the user device displayed health status. The digital interaction between gate-keeper and user (patron/attendee) may be a decoding of an encoded tag relayed from the user device by the gate-keeper device or terminal using any number of conventional short-range wireless protocols (RF, ZigBee, BlueTooth, etc.). The digital interaction between user and gate-keeper may further comprise (1) the user and gate-keeper devices being within a wireless communication short-range; (2) the user transmitting a signal with a tag to the at least gate-keeper device; (3) the gate-keeper device accepting the signal with the tag; (4) decoding the tag by the at least gate-keeper device to trigger a digital event comprising at least one of a sound, vibration, flash, signal, symbol, color, text, curated line of static, dynamic or scheduled images (user face or other distinguishing feature, for instance), or video content for display or download on the gate-keeper device, or for upload over a network to a registry for dashboard provisioning. The gatekeeper may scan any one of a barcode, QR code, etc. in order to trigger the digital interaction/event or decode the tag from the user to gatekeeper for further authentication.

The digital interaction may be between user-to-user devices (U-U), rather than between user and gate-keeper devices (U-G). The U-U interaction scheme may involve the 4 steps described above for the U-G scheme, with an additional digital event marking exceeding a threshold distance/duration between user devices marked “unsafe” based on the pre-defined distancing rule and health status display of each device. The “unsafe” marking may be based on a health status display of unvaccinated, untested, inconclusive testing, positive testing, etc.,—of at least one of the user devices. The digital event marking the unsafe interaction may be signaled by any one of a color/symbol-coded display, flashing, or audible alert—based on a pre-defined protocol.

In other embodiments, an off-line feature is provided—allowing a user to engage in any of the above described encryption/decryption/download schemes while on-line for local device storage of the native/coded certification/test result for a future off-line display. This allows for gate-keepers to engage in a “safe-status” check even in more remote “internet-dark” locations. While perhaps not a real-time decryption/download from the public health registry, the gate-keeper may ensure relative recency by a time-specific coded display scheme. For instance, based on a pre-defined schedule/calendar, each specific date/date may correspond to a specific color/symbol to ensure a recent download/decryption. For instance, if Tues, January 19^(th) corresponds to a blue circle coding for a positive vaccination or negative test (+ vacc./− test) according to the schedule/calendar, then an off-line display of a yellow square may not gain entrance for the user due to the fact that the schedule/calendar indicates that the yellow square is the + vacc./− test code from the previous week. In some embodiments, the on-line decryption/download and/or storage (on-line remote/off-line device) may be achieved with use of a blockchain-type immutable ledger of node status results across a network.

FIG. 27 illustrates an exemplary magnetic nanoparticle in accordance with an aspect of the invention. As shown, the magnetic nanoparticle comprises a core iron oxide nanoparticle 2702; a coating 2706 around the iron oxide core 2702 and being impregnated/embedded with a therapeutic/vaccine agent 2704 for targeted delivery with certain cationic/magnetic elements 2708 for further augmentation of magnetic properties. Magnetic nanoparticles or superparamagnetic nanoparticles based on a core consisting of iron oxides (SPION) can be targeted through external magnets. SPION are coated with biocompatible materials and can be functionalized with drugs, proteins or plasmids.

While the magnetic properties are conventionally used for targeted delivery, the magnetic properties may be exploited for confirming the presence of a therapeutic/vaccine via display of a symbol/color code—with each category of therapeutic/vaccine associated with a designated magnetic property displaying a pre-defined and unique symbol and/or color. For instance, a higher intensity Iron Oxide detection may suggest the presence of COVID-19 vaccine via a green square or circle (for instance), whereas a lower intensity detection may suggest a different vaccine (flu/yellow circle, for instance). Any person of ordinary skill may appreciate the fact that varying intensities and other magnetic properties of the same magnetic nanoparticle may confer detection of different therapeutics/vaccines, or varying magnetic nanoparticles may confer different therapeutics/vaccines.

Furthermore, while not shown, the converted field-specific electrical signal (magnetic properties, including for magnetic intensity) and pre-defined permission or rules (NVP signaling protocol, for instance) may further trigger downstream digital events, such as registering a user health status on a local or wide registry for contact tracing purposes, etc.

This therapeutic/magnetic relationship is further elaborated on in FIG. 28, which illustrates an exemplary magnetofection schematic in accordance with an aspect of the invention. Magnetofection is a transfection method that uses magnetic fields to concentrate particles containing nucleic acid and in-utero samples to the target cells. As shown, the cellular uptake of the genetic material is accomplished by endocytosis and pinocytosis. The nucleic acids are then released into the cytoplasm by different mechanisms depending upon the formulation used. However, it is an object of the invention to exploit the technique of magnetofection for detecting a presence of a corresponding therapeutic/vaccine.

Any number of devices may be disposed with an integrated magnet (optionally, integrated magnet with transducer for signal conversion) or may be paired (wired/wirelessly) with a magnet portion. For instance, a line-of-sight digital badge device 2802 may be disposed within the device housing, or on the (circular or square) device casing, to detect a specific magnetic characteristic for confirmation of a specific therapeutic/vaccine. In cases where the form factor prevents disposing a magnet, the device may couple to an external magnet for a visual confirmation via the color/symbol coded display on the display device (see smart watch 2804 paired wirelessly, mobile device 2808 paired physically via a magnet stick 2806). Devices may be any one of line-of-sight (LoS) device or a circle-of-sight (CoS) device, wherein the LoS device is any one of a badge, smart watch, integrated smart glass, mobile device, fixed access point or terminal, hand-held scanner, locket housing a watch, clip-on element, or arm-band, and wherein the CoS device is any one of a fixed access point or terminal, ear buds, over the ear head phones, clip-on element, or arm-band.

In one embodiment, a green-colored, symbol-coded display suggest a positive detection of a magnetic nanoparticle, such as an Iron Oxide core (with specific frequency/intensity), within a therapeutically-embedded coating. Based on a pre-defined rule, any number of color and symbol coded displays may be suggestive of any number of embedded therapeutics. For instance, a higher intensity Iron Oxide detection may suggest the presence of COVID-19 vaccine via a green square or circle (for instance), whereas a lower intensity detection may suggest a different vaccine (flu/yellow circle, for instance). Further yet, any intensity of Iron Oxide detection may suggest the presence of COVID-19 vaccine via a green display, whereas any intensity detection of a different nanoparticle (nickel-based, for instance) may suggest the presence of the Flu vaccine via a yellow display (for instance). In other embodiments, in addition to the pre-defined symbol and color-codes, a QR code may be generated and presented as a pre-cursor for triggering a downstream digital event (further validation for a gate-keeper, etc.). In other embodiments, the QR code is an example of a downstream digital event. In yet other embodiments, the display may be strictly audible. And further yet, the display output may comprise of a single-blind display, whereby the gate-keeper may be the only one who is aware of the color and symbol codes as an assurance against fraudulent displays. Other embodiments may simply output a QR code for scanning to further validate. Finally, a text based display confirming a positive magnetic detection of a therapeutic/vaccine is possible.

As shown in FIGS. 29 and 30, which are exemplary method flow diagrams detailing the steps involved in the color/symbol-coded health status display, comprising the steps of disposing a magnet within a housing of the user-worn or carried device, configured to detect a magnetic field supercutaneously, wherein said field is generated by an interaction of the magnet with magnetic nanoparticles of a delivery agent delivering a therapeutic or vaccine intravenously; converting the detected magnetic field into a field-specific electrical signal; and outputting at least one of a pre-defined color, symbol, or audio-coded display on a display portion of the user-worn or carried device signaling the user health status based on the converted field-specific electrical signal.
